Smart thermostat costs per brand

The thermostat market is becoming increasingly competitive, with hundreds of thermostat devices being sold every day. Some are designed for small flats and others for large office buildings, and each has a very different price depending on its features. Although smart thermostats have come onto the market relatively recently, some brands stand out for the quality they offer.

Cost Honeywell Thermostat

If you need a smart thermostat that comes with an abundance of features at an affordable price, Honeywell thermostats have everything you need at a price that fits your budget. Although it also requires the installation of a C-wire, it does an exceptional job for the €68 - €200 price range in which it comes.

Cost of Nest Thermostat

Nest smart thermostats are the best thermostats for those who want to strike a balance between affordability and looks. They currently have different types starting at around €109 for the simpler model, while the other, more modern-looking model costs around €229. The Google Nest Learning Thermostat with a price tag of €162 has all the basic functions that most units have.

Cost to install Smart Thermostat

Installing a smart thermostat starts with connecting the wires to their respective ports and attaching the mounting plate to the wall. While this can be a do-it-yourself job, electricians and Smart home specialists have the knowledge and experience to do this in the safest way, so it is recommended to hire one for the job. Most electricians charge a fixed rate of €65 for small jobs, or between €65 and €79 if you agree on an hourly rate. 

Type of cost
Programmable thermostat €20-€170
Smart thermostat £69-€250

Replacement costs for smart thermostat

If you're replacing an existing smart thermostat and there are already wires available for installation on your walls, the process is quite simple and quick. One will simply disconnect the old model from the mounting plate and connect the existing wires to the mounting plate of the new unit. As replacing an existing thermostat is a relatively simple job, it would cost around €85 for an electrician to replace it with a new one.

However, if you are replacing an older model and an additional C-wire installation is required, the installation will take longer and cost more. As time goes on, the installation costs would add up to €100, so the C-wire installation would add an extra €70 to €100 to the total cost, depending on the type of thermostat you are replacing.

Smart thermostat versus standard thermostat

Although people often think they are the same, smart thermostats and programmable thermostats are different. The main difference between the two is that programmable thermostats allow you to set a preferred temperature for a specific time of day, while smart thermostats can remember your preferences over time and apply them automatically. They basically serve the same purpose, but smart devices go a step further with touchscreen options and automatic temperature settings.

The additional features of smart thermostats are also reflected in the cost. While programmable thermostats can be found for as little as €20, smart thermostats can cost up to €250, depending on the model and features.
